Method: Shotgun metagenomic sequencing (CLIA 21D2062464); not cleared or approved by the FDA. Results reflect relative microbial abundance for wellness education purposes. Not intended to diagnose or treat disease and not a substitute for clinical consultation. Microbial associations are based on emerging scientific research and may change over time.
A derived biomarker is a value that is calculated from other directly measured biomarkers rather than being measured directly in the lab.
Key benefits of Ruminococcus testing
- Fiber-degrading beneficial commensal genus tracking
- resistant starch fermentation capacity assessment
What is Ruminococcus?
Ruminococcus is a genus of fiber-degrading gram-positive anaerobes. Key species like Ruminococcus bromii are primary degraders of resistant starch in the gut, enabling broader SCFA production by the microbiome community. Detected by shotgun metagenomic sequencing.
Why is Ruminococcus important?
Ruminococcus species - particularly R. bromii - are keystone fiber degraders that break down resistant starch into fermentable sugars used by many other gut bacteria. Higher Ruminococcus abundance may reflect a microbiome well-equipped to process resistant starch-rich foods.
What insights will I get?
Your Ruminococcus level may indicate the capacity of your gut microbiome to process resistant starch from foods like cooked and cooled potatoes, legumes, and green bananas. Low levels may suggest reduced resistant starch fermentation capacity.
